Bahrain's Manama municipality is upgrading its waterfront and boulevard cleaning, and city fleets want street washers that do not add diesel fumes to the streets they clean, which makes a 282 kWh electric washing truck a practical municipal upgrade. The KT7A electric washing truck carries a CATL LFP battery and an LvKong motor sized for steady pump and chassis duty, delivering an EV truck that covers long dawn cleaning routes on a single charge.
Manama runs washing trucks on 40-70 km loops through the waterfront, souq districts and embassy boulevards, mostly at low speed before the morning traffic builds. Those quiet, stop-frequent routes are ideal for battery-electric trucks: the pump load is steady, regenerative braking recovers energy at every turn, and the silent chassis lets crews work at dawn without disturbing residents. A diesel washer on this duty burns 0.45-0.50 L/km, and at Bahraini diesel near $0.95/L that is about $0.45/km. The KT7A cuts that to roughly $0.15/km at municipal electricity of $0.09/kWh and 1.2-1.4 kWh/km.
Because the truck often idles the pump while parked at a plaza, a diesel unit wastes fuel merely running the engine to drive the washer. The KT7A drives the pump from the high-voltage pack, so the chassis stays silent at the kerb while cleaning proceeds.
| Specification | KT7A electric washer | Diesel washer |
|---|---|---|
| Battery capacity | 282 kWh CATL LFP | N/A |
| Motor power (LvKong) | 282 kW | ~160 kW diesel |
| Water tank | 8-10 m3 | 8-10 m3 |
| Route range | 110-160 km | ~400 km |
| Energy use | 1.2-1.4 kWh/km | 0.47 L/km |
| DC fast charge | 10-80% in 55-65 min at 180 kW | N/A |
| FOB price range | $70k-90k | $50k-65k |
The 282 kWh pack carries the CATL 8-year or 4,500-cycle warranty. On a single daily municipal shift the KT7A reaches the cycle floor in roughly eight years, exceeding the typical ten-year life of a washing chassis.
A single 180 kW DC fast charger at the municipal depot supports a fleet of KT7A units on rotating shifts; a 10-80% top-up takes 55-65 minutes during the midday maintenance window. Overnight charging at $0.09/kWh drops per-km energy cost below $0.13. For fleets scaling beyond five trucks, a 240 kW charger pair splits the dawn dispatch queue. Buyers can also review our Gulf electric truck market guide for regional import and warranty routing through the UAE hub.
| Cost line | Diesel washer | KT7A electric |
|---|---|---|
| Energy per 110 km | $50 | $16 |
| Maintenance per year | $6,800 | $4,200 |
| Emissions per day | ~50 kg CO2 | 0 at tailpipe |
Across 200 working days the KT7A saves about $13,200 a year on energy and maintenance versus a diesel washer. Against the $20k-25k FOB premium, payback arrives in under two years on a single daily shift, and the zero-emission profile strengthens any green-tender scorecard. Bahraini fleets gain a quieter, cleaner washer without changing their route plan.
The KT7A ships CBU via the UAE to Bahrain and we assist with tender documents, LvKong motor training and CATL BMS handover. Spare modules are held at the Gulf hub. FOB pricing is $70k-90k by tank and pump spec.
An electric washing truck removes the diesel engine's oil, filters, injectors, turbo, EGR and exhaust after-treatment - the parts that drive most unscheduled breakdowns on low-speed municipal routes. Our fleet data shows EV trucks cut scheduled maintenance by 35-40% versus a diesel equivalent, which on a washer running 200 days a year is roughly $2,600 in saved workshop bills. The LvKong motor's sealed drivetrain also avoids the pump-bearing wear that shortens diesel washer life in Gulf heat.
| Year | CATL pack health | Residual value |
|---|---|---|
| Year 1 | 100% | 80% of FOB |
| Year 3 | 92% | 60% of FOB |
| Year 5 | 84% | 42% of FOB |
| Year 7 | 78% | 30% of FOB |
The CATL 8-year warranty protects the 282 kWh pack to 78% state of health at year seven, by which point most municipalities have recovered the FOB premium several times over on fuel and maintenance. A 30% residual at year seven keeps the unit financeable when you refinance or trade it into a second owner.
Lead time from our Xi'an plant via the UAE to Bahrain is typically 50-70 days CBU. We hold spare battery modules at the Gulf hub so a fault never idles a municipal washer for more than a few days.
Charging cost scales with your municipal tariff, and the KT7A rewards cities that charge off-peak overnight at the Manama depot. At $0.09/kWh a full 10-80% top-up of the 282 kWh pack costs about $20 and delivers 110-160 km of route, or roughly $0.13-0.15 per km in pure energy. Move to $0.06/kWh solar and that falls below $0.10/km, far below diesel washer math.
| Tariff | Cost per 110 km | vs diesel |
|---|---|---|
| $0.09/kWh grid | $13 | save $37 |
| $0.06/kWh solar | $9 | save $41 |
| $0.12/kWh peak | $17 | save $33 |
Even at peak grid rates the KT7A beats diesel on Manama routes, and most municipal depots can lock an off-peak block that lands cost near the solar figure.
If your Manama routes run 40-70 km low-speed loops from a municipal depot, the KT7A is the right first electric washer for Bahraini city fleets. The 282 kWh CATL LFP pack, water-recycling option and 42 C Gulf rating are proven on waterfront boulevards, and the sub-two-year payback plus green-tender compliance strengthen any bid. We recommend starting with one paid trial unit, validating the overnight charge window, then scaling to a full shift as chargers land.
For the Manama municipal fleet, the KT7A electric washing truck turns daily street and waterfront cleaning into a silent, clean, low-cost duty. With a 282 kWh CATL LFP pack, water-recycling options and a sub-two-year payback, it is the right first electric truck for Bahraini city fleets.

Every Dongfeng electric truck we ship is covered by an 8-year or 4,500-cycle battery warranty on the CATL LFP pack, plus 3 years on the LvKong motor and controller. Shaanxi Fenghan Trading keeps a rotating stock of high-wear parts — brake pads, filters, suspension bushings and charging connectors — in Xi'an for 72-hour dispatch by air freight. Buyers receive an English service manual, wiring diagrams and video-based technician training for their local workshop team, and our engineers answer diagnostic questions on WhatsApp within one working day. For fleet orders of five units or more we include a free on-site commissioning visit to set up chargers and train drivers.
