12 Essential EV Accessories Every Electric Car Owner Must Buy in 2025.

Whenever we buy EVs, companies give some basic EV accessories such as charging cable, tire kit, and tool kit. But that’s not enough to maintain your EVs. Thus for maintaining the batteries and overall efficiency of EVs, we have listed out some important accessories which companies do not provide us. 

NOTE: All the accessories mentioned below are certified according to industry standards, BIS norms, and ARAI safety guidelines. All these accessories are technically proven real-world tested. 

EV Battery Health OBD Dongle (EV-Specific)

EV-specific OBD dongles are made according to OBD-II + ISO 15118 protocols. These are very important because EV batteries generally degrade because of cell imbalance and thermal stress. Here EV-specific dongles come into play as they provide. 

• State of Heath (SOH)
• Battery Temperature (Min/Mid/Max)
• Cell Voltage Deviation (>0.03V = imbalance alert)
• Regen Performance
• Charging Curvv
• Real Inflow/Outflow Data

All this information is never provided by EV companies as there are multiple real-world cases. Nexon EV owners detected early cell imbalance, whereas ZS EV owners often notice overheating through DC charging, and XUV400 owners experience thermal throttling over 47 Degree. 

Recommendations: CarScanner EV Mode, EVNotify + OBDLink CX, Veepeak BLE (BIS-Certified). 

EV Fire Safety Blanket (High-Temperature Rated)

Standard: EN 13501-1 / UL 94-V0

The lithium battery fire cannot be controlled from water thus there are EV fire blankets which can handle peak temperatures of 1,100 Degrees. These are used by big EV manufacturers such as Tesla, European charging stations, and Hyundai/Kia service.  Let’s understand some of the benefits

• Oxygen Supply Cut
• Instant control over spreading of fire. 
• Life-saving especially in Basement parking situations. 

Battery Undershield / Skid Plate

Standard: AIS-038 Rev 2

The maximum weight of EV batteries ranges from 300-450 Kg. Thus it carries many risks of getting damaged or punctured by a stone hit. Let’s understand the verified repair cost for the following popular models. 

• Nexon EV Pack: Rs 2.6 lakh. 
• MG ZS EV Pack: Rs 4.1 lakh.
• BYD Seal: Rs 5-6 Lakh. 

The aftermarket skid plate protects the batteries from highway debris, potholes and rough village roads. 

High-Voltage Cable Armor / Rodent-Proof Sleeve

Standard: Heat-Resistant 200 Degree Fire-Resistant 

The original HV cable is quite critical which can be easily destroyed by rodents. Thus these sleeves protect the HV cable from rats, water splash & stone hits. There are real life cases of popular models 

• Nexon EV HV Cable: Rs 18,000 repair
• ZS EV Cable: Rs 24,000 repair 

Thermal Reflective Battery Insulation Mat

The Indian summers witness peak temperatures of 42-48 Degree and due to which, the temperature of parked EVs rise to 4-8 Degree. Thus the thermal mat reduces the extra heat by 

• Overall reduction of temperature by 3-5 Degrees. 
• Improves Charging. 
• Prevents Throttling above 45 Degree. 

EV Ceramic Brake Pads (Rust-Free)

Due to Regen braking, there is a less usage of normal pads which leads to moisture deposit, rust, and grinding noise. In Europe and the US EV community, these are very common. The ceramic pads are basically

• Rust-resistant
• Better Low-Temperature Performance
• Last 2X longer. 

Smart Portable Charger (BIS-Certified)

Standards: BIS IS 17017-1, IEC 61851-1

Stock Chargers are basically 1.1 kW, thus it’s very important to have smart chargers which are perfect for apartment owners and road trippers. They provide support of 

• 3.3 kW / 7.3 kW
• Load Balancing
• Scheduling
• Auto-Cutoff at 80% (Battery-Focussed)

EV 12V Trickle Charger 

All EVs have a small 12V battery and if the EV is parked for 2-3 weeks, then the particular 12V battery can be dead and this has happened in Nexon EV and MG ZS EV which can further lead to

• Car start issues
• BMS errors
• RSA call required

Thus Trickle charger keeps the 12V battery healthy and uptime for every situation. 

Ultrasonic Rodent Repeller (EV Safe)

Standard: 20-60 kHz

It protects critical wiring faults done by rats and rodents thus it is important to install motor bay/ underbody. 

Battery Ventilation Booster (Garage Heat Extractor)

Basement charging can lead to heat traps which can affect the battery performance. Thus ventilation fans are helpful in 

• Faster Charging
• Lower Battery Stress
• Cooler Garage Temperature

IP67 Waterproof Charging Brick Case

The stock chargers are not waterproof and water or rain splash can create short circuit, thus usage of IP67 case provides protection towards dust, water and shock prevention. 

Charging Gun Dust Guard (Port Protector)

Frequent Dust in the A/C port can cause the risk of slow charging and excessive heat. Thus the port protector helps to keep pins clean by ensuring effective charging.
